The Ity CIL project feasibility and optimisation studies have been conducted by Endeavour Mining to analyse the economic viability of constructing a straight forward gravity circuit/carbon-in-leach (CIL) plant as an alternate ...
The facility process description, including the carbon-in-pulp, carbon-in-leach (CIP/CIL) circuit can be found in the attached McLaughlin Mine General Information Summary. The ultimate waste discharge for all circuit operations is the tailings pond. On-site laboratories are used to perform analytical testing of mining ores and process fluids.
Under the consider that pulp concentration is 40%, lime is 7kg/t, and sodium cyanide is 4kg/t, leaching for 24 hours, the final leaching rate of gold is 93.40%. Grinding stage uses two-block close circuit grinding and classification, grinding production flows to thickener after screening by dust screen. The underflow is pumped to leaching ...
As per the new law notified by the government, power plants have to give a three weeks prior notice to the buyers about the proposed impact in the tariff to be recovered under CIL.
